Both are completely viable options – the finished game promises to even allow you to become friends with all the bosses. The combat system is unlike anything you’ll of seen before – when battles commence you have the option to fight or talk your way out of trouble. The glorious retro pixel art visual style of UNDERTALE belies some truly innovative gameplay and game design. UNDERTALE is a wonderfully inventive RPG which draws favorable comparisons to the MOTHER ( Earthbound) series, that features a witty story, interesting puzzles and a truly innovative skill-based combat system that allows you to befriend your attackers.
